Particle MCMC for Bayesian Microwave Control [PDF]

, 2014
We consider the problem of local radioelectric property estimation from global electromagnetic scattering measurements. This challenging ill-posed high dimensional inverse problem can be explored by intensive computations of a parallel Maxwell solver on a petaflopic supercomputer. Then, it is shown how Bayesian inference can be perfomed with a Particle

Anomaly Detection of Underwater Gliders Verified by Deployment Data [PDF]

arXiv, 2022
This paper utilizes an anomaly detection algorithm to check if underwater gliders are operating normally in the unknown ocean environment. Glider pilots can be warned of the detected glider anomaly in real time, thus taking over the glider appropriately and avoiding further damage to the glider.

Remote sensing for oceanography: Past, present, future [PDF]

, 1984
Oceanic dynamics was traditionally investigated by sampling from instruments in situ, yielding quantitative measurements that are intermittent in both space and time; the ocean is undersampled.

A model of melt pond evolution on sea ice [PDF]

, 2004
A one-dimensional, thermodynamic, and radiative model of a melt pond on sea ice is presented that explicitly treats the melt pond as an extra phase. A two-stream radiation model, which allows albedo to be determined from bulk optical properties, and a ...

Use of virtual reality to engage undergraduate students in environmental field experiences

Future in Educational Research, EarlyView.
Abstract Field‐based experiences enhance cognitive and affective skill sets of undergraduate students. Although field‐based learning is a highly effective pedagogical modality, it is not accessible to all students, necessitating the development and evaluation of alternate modalities that convey equivalent benefits.

Mesoscale Ocean Altimetry Requirements and Impact of GPS-R measurements for Ocean Mesoscale Circulation Mapping [PDF]

arXiv, 2002
In the framework of the PARIS Beta project, fundamental milestones have been reached for the definition of future GNSS-R (Global Navigation Satellite System signal Reflections) altimetry missions (the PARIS concept). The most important one is the confirmation of the significant impact that GNSS-R data can have on mesoscale oceanography, as we discuss ...

Viral metagenomics of Okavango Delta water pans reveal novel insights into wildlife disease potential

iMetaOmics, EarlyView.
Botswana's Seronga region saw a mass elephant die‐off potentially linked to water sources. This study analyzes Okavango Delta metagenomes, uncovering a diversity of viruses and harmful pathogens. Findings highlight the importance of understanding viral ecology in these waters and support One Health's objective in protecting human, animal, and ecosystem

Long‐Term Effects of Land Use and Cover Change and Dam Rupture on Ichthyofauna in a Neotropical Stream

International Review of Hydrobiology, EarlyView.
ABSTRACT This study evaluates land use and land cover (LULC) changes and their impacts on the fish community of a neotropical stream in the Sorocaba River basin, Brazil, from 2006 to 2023. The watershed experienced landscape changes over time, categorized into four periods: rural interventions, urban interventions, restorative interventions, and post ...
